目的对与云南烟草丛顶病害病原相关的病毒粒体进行初步定性.方法应用电子显微镜、PAGE-SDS电泳和甲醛变性电泳.结果发现该病毒为一直径在26 nm左右的球状粒体,病毒外壳由1种分子量在55 kDa左右的蛋白组成,病毒壳内核酸由3种RNA组成.结论该病毒颗粒与病害发生和病原均有着密切的关系.

A virus particle associated with tobacco bushy top disease inYunnan was analyzed by electromicroscopy and electrophoresis. An isometric virus particle with a diameter of 26 nm was obtained from the Aphid on infected tobacco plants. A coat protein band with a molecular weight about 55 kDa was obtained by PAGE-SDS electrophoresis, and three RNA band...
